Here is the second Gregg Shorthand version of A Christmas Carol. It was published in 1931. It matches the 1929 Gregg Shorthand Anniversary Manual. This version is heavily abridged, including shorthand for approximately 40% of the English novel.
The first Gregg Shorthand version of A Christmas Carol was published in 1918. It matches the 1916 Gregg Shorthand Manual with plates by Winifred Kenna. The same shorthand plates were used in "Short Classics in Shorthand" (1927), which featured five short novels. The first Gregg Shorthand version is heavily abridged, including shorthand for approximately 20% of the English novel.
This 1931 book entered the public domain as soon as it was first published. There is no copyright notice in the book. Any book first published in the US before January 1, 1978, without a proper copyright notice immediately went into the public domain at the time of publication. There are also no copyright notices in any of the other individual Gregg Shorthand novel versions of existing works, such as Alice in Wonderland, Rip Van Winkle, the Great Stone Face, etc. All copyrights belonged to the original material. Back then, the US Copyright Office did not allow Gregg to copyright shorthand novels based on existing literary works.
